Abstract

Unscented and low scented malodor control compositions are provided. The malodor control compositions are suitable for a variety of applications, including use on plastic films or in fabric and air freshening products.

Claims

1. A malodor control composition comprising:

a perfume mixture comprising benzophenone, methyl palmitate, farnesol, vetivert acetate, and undecylenic aldehyde for reducing malodors.

2. The malodor control composition of claim 1 further comprising cedryl methyl ether, florhydral, helional, vertofix couer, and mixtures thereof.

3. The malodor control composition of claim 1 wherein said perfume mixture further comprises at least one volatile aldehyde selected from the group consisting of floral super, 2-ethoxy Benzylaldehyde, 2-isopropyl-5-methyl-2-hexenal, 5-methyl Furfural, 5-methyl-thiophene-carboxaldehyde, p-anisaldehyde, Benzylaldehyde, Cinnamic aldehyde, Decyl aldehyde, Ligustral, Lyral, Melonal, o-anisaldehyde, P.T. Bucinal, Thiophene carboxaldehyde, trans-4-Decenal, trans trans 2,4-Nonadienal, Undecyl aldehyde, and mixtures thereof.

4. The malodor control composition of claim 1 wherein said perfume mixture further comprises a volatile aldehyde mixture selected from the group consisting of:

intreleven aldehyde, florhydral, floral super, scentenal, cymal, and o-anisaldehyde (Accord A),

intreleven aldehyde, florhydral, floral super, scentenal, cymal, floralozone, adoxal, methyl nonyl acetaldehyde, melonal, and o-anisaldehyde (Accord B),

intreleven aldehyde, florhydral, floral super, scentenal, cymal, floralozone, adoxal, methyl nonyl acetaldehyde, melonal, flor acetate, frutene, helional, bourgeonal, linalool, benzaldehyde, and o-anisaldehyde (Accord C),

and mixtures thereof.

5. The malodor control composition of claim 4 wherein said perfume mixture further comprises about 1% to about 10% of Accord A, by weight of said perfume mixture.

6. The malodor control composition of claim 1 wherein said perfume mixture is present in an amount from about 50% to about 100%, by weight of said malodor control composition.

7. The malodor control composition of claim 1 further comprising an acid catalyst present in an amount of about 0.1% to about 1.5%, by weight of said malodor control composition.

8. The malodor control composition of claim 7 wherein said acid catalyst has a vapor pressure of about 0.01 to about 2 torr at 25°

C.

9. The malodor control composition of claim 7 wherein said acid catalyst is a carboxylic acid.

10. The malodor control composition of claim 9 wherein said acid catalyst is 5-methyl thiophene carboxylic acid.

11. The malodor control composition of claim 1 wherein said composition has a pH of about 4 to about 6.5.

12. The malodor control composition of claim 1 further comprising an ingredient selected from the group consisting of:

odor masking agents, odor blocking agents, diluents, and mixtures thereof.

18. A method of controlling malodors and providing a low scented composition comprising:

providing the composition of claim 1; and

contacting said composition with a malodor.

19. The method of claim 18 wherein said contacting step comprises about 5 mg to about 15 mg of said composition.

13. A plastic film comprising a perfume mixture comprising benzophenone, undecylenic aldehyde, methyl palmitate, vetivert acetate, farnesol, wherein said perfume mixture reduces malodors in the air.

14. The plastic film of claim 13 wherein said plastic film is LLDPE.

15. The plastic film of claim 13 wherein said plastic film comprises about 0.5 mg to about 50 mg of said perfume mixture.

16. The plastic film of claim 13 wherein said perfume mixture is present in the amount of about 5 mg to about 30 mg.
